THIS IS NOT MY ANSWER i got this from someone else but i think this will help u cause it’s from the same question:

We have our initial unit of speed: 343 m/s.

We want to find how many kilometers sound will travel when the air is at 68 degrees in five seconds.

Step 1: Multiply 343 by five. (1 sec. to 5 secs.)
343 * 5 = 1715

Step 2: Divide 1715 by 1000. (1 m. to 0.001 km)
1715/1000 = 1.715 km/5 secs.

At a temperature of 68°, sound will travel 1.715 km in 5 seconds.

Your answer would be B.

The triangles would be congruent, because the lines GH and FI are congruent and the angle H and I are the same, and since the line HI is shared by the two, it would then be SAS.

How to solve -6<-2x<14
algol13
Hey there! :) 

-6 < -2x < 14

We're trying to solve for x. To solve for x, we must isolate x.

So, let's divide everything by -2!

-6 ÷ -2 < -2x ÷ -2 < 14 ÷ -2

**Remember : when dividing by a negative number, you MUST switch the sign! So, if the sign is ">" then we switch it to "<" and the other way around **

3 > x > -7

So, our answer is : → 3 > x > -7

~Hope I helped!~

the coordinates of the vertices of a polygon are (2,4) (6,4) (6,0) and (2,0). The polygon is dilated with a scale factor of 3/2
svlad2 [7]
Take the first point (2, 4)  a scale factor of 3/2 will move the x coordinate 2 to 2*3/2  = 3 and the y coordinate 4 will  be moved to 4*3/2 = 6.
So the image of ( 2, 4) will be ( 3, 6)  TH other verices will move in the same fashion.
